Procedure

Following the procedure for 143, 2-[2-(2,4-difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-9-piperidin-4-yl-4,5-dihydro-2H-6-oxa-1,2-diaza-benzo[e]azulene hydrochloride was reacted with bromo acetamide. The crude product was subjected flash chromatography (SiO2, gradient 50 to 100% ethyl acetate in cyclohexane). Pure fractions were combined and concentrated in vacuo and the resultant residue dissolved in DCM and treated with 4M HCl in dioxane then diethyl ether. The resultant precipitate was collected by filtration to give 178 as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 9.86 (s, 1H); 8.48-8.43 (m, 1H); 8.30 (s, 1H); 8.05 (s, 1H); 7.85 (td, J=8.75, 5.93 Hz, 1H); 7.74-7.63 (m, 2H); 7.41-7.34 (m, 1H); 7.22 (d, J=2.30 Hz, 1H); 7.10 (dd, J=8.45, 2.35 Hz, 1H); 6.97 (d, J=8.39 Hz, 1H); 4.22 (t, J=5.00 Hz, 2H); 3.98 (d, J=4.37 Hz, 2H); 3.60 (t, J=12.26 Hz, 2H); 3.24-3.13 (m, 2H); 3.06 (t, J=4.95 Hz, 2H); 2.69-2.61 (m, 1H); 1.87 (s, 4H). LCMS: RT=7.46 min, M+H+=506
